A 4,074/62 17 Claims. ((11. 179-179) This invention relates to amicrophone having a handle which consists of two interfitting andpreferably detachably connected parts, one part-of which has protrudingelements about which the cable connected to the microphone capsule -canbe wound, according to the prior Patent No. 3,219,765 (application Ser.No. 185,588, filed April 6, 1962).

According to a feature of the invention covered by said prior patent, aholder for the connecting plug is provided between the protrudingelements of one part so that all parts of the microphone leading to theoutside are accommodated in a protective housing together with themicrophone when the same is not used.

The present invention is an improvement of the inven tion covered bysaid prior patent.

The embodiments disclosed in said prior patent do not exhaust thepossibilities which are inherent in the invention thereof. Specialadvantages are afforded, e.g., by a development of the handle microphoneaccording to said prior patent, which development will be describedhereinafter and is characterized in that the protruding elements of onepart have the configuration of an elongated tub, around the outside ofwhich the microphone cable is to be wound, whereas the internal recessdefined by said tub serves to accommodate the microphone plug connectedto the cable.

According to another feature of the invention, the tub is disposed inthe interior of the part which is similar to a box body and can beclosed by a shallow part similar to a box cover. The cover is suitablyhinged at one end to the other part so that the cover cannot be lost ormisplaced.

It has proved highly desirable if the free upper rim of the tub isslightly turned outwardly or provided with a small bead so that this rimand the inside wall of the part similar to a box body and provided withthe tub define a slot, the width of which is slightly smaller than thediameter of the microphone cable. In this case, it is not necessary totension the cable when it is being wound up, but it is sufficient tointroduce it under slight pressure into the slot. Because the width ofthe slot is somewhat less than the diameter of the cable, the latterwill not fall out of its holder under any circumstances. A similararrangement may be provided for the microphone plug, which isaccommodated inside the tub.

For this purpose, portions of the tub extending substantially parallelto the longitudinal axis of the tub may be provided on the inside withprojections, ribs or the like extending substantially parallel to saidaxis and restricting the opening through which the plug is inserted intothe space provided for its accommodation so that the plug can beinserted only under slight pressure into the internal cavity of the tub.In this case too, the plug cannot readily fall out of its container,because this is prevented by the protruding ribs.

T o facilitate the understanding of the invention, it will be describedmore fully hereinafter with reference to the accompanying drawing.

In the drawing, FIG. 1 is a sectional view taken on line AA of FIG. 2and showing the housing of the handle microphone according to theinvention.

FIG. 2 is a sectional view taken on line BB in FIG.

l and showing diagrammatically the complete handle microphone accordingto the invention,

FIG. 3 is a transverse sectional view taken on line C-C of FIG. 1.

The longitudinal sectional view shown in FIG. 1 shows the housing of themicrophone to consist essentially of three parts. The right-hand part 1defines a cavity 10, which is intended for accommodating a microphonecapsule, which is diagrammatically indicated at 21 in FIG. 2. Theopening 2 exposes the face of the microphone and may be covered with adecorative or protective grid. The left-hand part 3 of the housing issimilar to a box body and has in its interior the tub 5. As is alsoapparent from FIG. 1, the wall of the tub is slightly curved outwardlyso that a slot is defined between the inside wall of the box body andthe top rim of the tub. As has been described hereinbefore, this slot isso narrow that the microphone cable indicated at 23 in FIG. 2 can beintroduced only with slight pressure into the space 6. The partitionbetween the cavity 10 and the space 6 is formed with an open-ended slot22, shown in FIG. 2, through which thecable extends from the cavity 10into the space 6. The tub is formed at one end with an openended slot 4,through which the cable extends to the microphone plug in the interiorof the tub. The microphone plug is indicated at 24 in FIG. 2 and whennot used is disposed in the space 7 defined by the tub and is heldagainst falling out by the projections or ribs 9 disposed on thoseportions of the tub wall 5 which extend substantially parallel to thelongitudinal axis of the microphone housing. The projections or ribs 9are particularly clearly shown in the transverse sectional view shown inFIG. 3. FIG. 2 gives a good impression of the plan form of the housing.

Forthe sake of completeness, reference be made once more to FIG. 1,which shows the third housing part 8 consisting essentially of a shallowbox cover, which is suitably hinged at 11 so that it cannot be lost.

The wall of the part 3 is formed with an opening 12, through which themicrophone cable extends out in use while the cover is closed. Thisresults in a pleasing appearance of the microphone also in use, withoutany projecting parts, and in a better protection of the microphone cableand the plug than is afforded by the embodiments described in said priorpatent.

It will be understood by a person skilled in the art that the materialof the tub 5 must be sufi'iciently resiliently flexible to yieldlaterally when the plug 24 is inserted into the plug space 7. A materialsuitable for this purpose is impact polystyrene.
